Method for determination of cadmium and lead in stack gas

This document establishes a standardized analytical procedure for quantifying the concentrations of cadmium and lead within exhaust emissions. The methodology is designed to ensure consistency and reliability in the measurement of these specific heavy metals. It provides detailed instructions regarding sample preparation, the selection of appropriate instrumentation, and the step-by-step operational processes required for accurate determination. The protocol addresses potential interferences and outlines necessary quality control measures to maintain data integrity throughout the analysis. By adhering to these specified techniques, laboratories can achieve comparable results, which supports regulatory compliance and environmental monitoring efforts. The scope covers the determination of these pollutants in gaseous effluents, offering a systematic approach for analytical chemists. This framework facilitates the assessment of emission levels without evaluating the broader impact or significance of the standards themselves.
